Extended temporal coarse-graining in a stratified and confined plasma under thermal fluctuations
Luca Barbieri, Simone Landi, Lapo Casetti +1
We present an extended investigation of a recently introduced model of gravitationally confined, collisionless plasma (Barbieri et al. 2024a), which showed that rapid temperature f…
Temperature inversion in a confined plasma atmosphere: coarse-grained effect of temperature fluctuations at its base
Luca Barbieri, Emanuele Papini, Pierfrancesco Di Cintio +3
Prompted by the relevant problem of temperature inversion (i.e. gradient of density anti-correlated to the gradient of temperature) in astrophysics, we introduce a novel method to…
Spacetime Hall-MHD turbulence at sub-ion scales: structures or waves?
Emanuele Papini, Antonio Cicone, Luca Franci +4
Spatiotemporal properties of two-dimensional (2D) Hall-magnetohydrodynamic turbulence at intermediate plasma are studied by means of Fast Iterative Filtering, a new technique…
Spectral transfer and Kármán-Howarth-Monin equations for compressible Hall magnetohydrodynamics
Petr Hellinger, Emanuele Papini, Andrea Verdini +4
We derive two new forms of the Kármán-Howarth-Monin equation for decaying compressible Hall magnetohydrodynamic (MHD) turbulence. We test them on results of a weakly-compressible,…
Multidimensional Iterative Filtering: a new approach for investigating plasma turbulence in numerical simulations
Emanuele Papini, Antonio Cicone, Mirko Piersanti +4
Turbulent space and astrophysical plasmas exhibit a complex dynamics, which involves nonlinear coupling across different temporal and spatial scales. There is growing evidence that…
Can Hall Magnetohydrodynamics explain plasma turbulence at sub-ion scales?
Emanuele Papini, Luca Franci, Simone Landi +3
We investigate the properties of plasma turbulence by means of two-dimensional Hall-magnetohydrodynamic (HMHD) and hybrid particle-in-cell (HPIC) numerical simulations. We find tha…
